LOG-HANDLING MACHINE.

Specification of Letters Patent.

Patented Dec. 11, 1906.

Application filed October 17, 1906. Serial 110.283.164-

l all w/wm, it may concern:

Be it known that I, GEORGE W. BUTT, a citizen of the United States, residing at N orfolk, in the county of Norfolk and State of Virginia, have invented certain new and useful Improvements in Log Handling Machines, of which the following is a specification.

My invention relates to machines for handling logs and timber.

The object of my invention is to provide a machine by which cars may be loaded or unloaded at the front or boom end of the ma chine, the empty cars being removed out of the way by passing beneath the machine; also, the platform of the apparatus may be so lifted to permit a loaded logging-train and a light locomotive, such as is usually employed in lumber districts, to pass beneath.

The invention is also adapted to be readily transported upon a log or fiat car to any desired point and may be worked on embankments and trestles.

The invention consists of other novel features and advantages, which will be more fully understood by having recourse to the accompanying drawings, forming a part of this specification, in which Figure 1 is a side elevation. Fig. 2 is a plan, and Fig. 3 is a cross-section on the line 1 2 in Fig. 2.

In the drawings like reference-numerals indicate similar parts in all the views.

1 is a platform or floor supported upon the box-girders or double I-beam sills 2, which for strength are reinforced by the lattice bars or plates 3, as shown in Fig. 2. The ends of the sills or beams 2 project a short distance from edge of the platform, and between the double beams there are placed vertical channel-bars a, which form guides for the supporting legs or standards 5 in order to permit them to be slidably mounted in the channels,-being held in place therein by the short bars or straps 6. The standards 5 are braced transversely by means of the rods 6, Figs. 1 and 3, having collars or shoulders 6 Fig. 3, and held in position by the nuts 6 y In this manner the upper portions of the standards are rigidly connected, and I may use braces disposed longitudinally, if desired.

The lower ends of the legs or standards are bent into a right-angle or square elbow 7, so as to extend a short distance under the platform 2. The lower ends are provided with a cross-bar 8, Figs. 1 and 3, at right angles to the bent part 7, so as to enable the standards to rest upon one or more of the railroad-ties, which form the foundation of the machine when at work loading, unloading, skidding, and the like. To prevent undue strain upon the angle portions of the legs, I provide triangular plates or gusset's 9, riveted or bolted to the vertical portions and the angle ends 7.

10 represents sheave wheels rotatorily mounted on the upper ends of the four or more standards or legs 5, over which pass ropes or chains 11, preferably wire-strand cables, having one of their endsfastened to an eye or ring bolt 12, placed at various points on the platform, the other ends of the ropes passing around drums, as at 13, 1 1, 15, and 16, so that when the drums are rotated the platform is raised at each corner or at more points, according to the size and weight of the machine.

As shown by the dotted lines in Figs. 1 and 3, the platform may be lifted to enable a train of logging-cars to pass beneath it. For example, when the machine is in use loaded cars are pushed to the front or boom end for unloading, after which the empty cars are allowed to pass under the platform to the rear of the machine out of the way, the cross pieces or bars 8 on the lower angle ends of the legs or supports 5 resting upon the crossties of the railroad;

\Vhen it is desired to transport the machine, a log or flat car is run under the platform, which is then lowered until it rests upon the car, and in orderto lift the standards, so as to clear obstructions when being moved, I provide cables or ropes 17, passing around the drums 13, 14, 15, and 16, and the sheaves 18, the free ends of the rope being made fast to the bottom of the platform, as at 19. The sheaves or pulleys 18 are mounted on suitable pins near bottoms of the standards 5. After the platform is resting on the car the drums are rotated a suflicient amount to wind the ropes 17 which lifts the legs or standards and their cross-pieces 8 from the ties a degree necessary to clear them.

The drums or pulleys 13, 1 1, 15, and 16 are supported on the ends of the shafts 20 and 21, respectively, and so arranged as to cause the drums to project a short distance beyond the edge of the platform, as shown in Figs. 2 and 3.

22 represents sprocket-Wheels or sheaves on the shaft 21 and connect by chains or link IIO belts 23 to the sprocket-wheels 24 on shaft of the hoisting-drum 24 25 is a ratchet-wheel on the shaft 21, which is engaged by the pawl 26.

27 is a hoisting-drum geared to the drum 24 and has sprocket-wheels 28 up on its shaft,

the

which rotate the wheels 29 on the shaft 20 by means of the belt 30. The shaft 20 is likewise provided with a ratchet-wheel 31 and pawl 32 for holding the platform at any desired height and works in conjunction with the ratchet-wheel 25 and pawl 26.

33 is a boiler furnishing steam to the double engines 34, by which the drums 24 and 27 are rotated.

35 is a boom or derrick arm of the usual construction.

The engines 34 being no part of myirivention I do not show thevarious clutch mechanism and reversing-gear generally used, asI

'may use any suitable engines in proper connection with the parts pertinent to this inv'en tion.

Having. described my invention, What I claim, and desire to secure by Letters Patent, is

1. A log-handling machine comprising a plurality of continuous reinforced vertical supports or standards having their lower ends bent to form a right angle, or L-shaped for bearing directly on the ties and a verticallymovable platform or floor supported by said standards.

plurality of vertical standards or supports having their lower ends bent at an angle, triangular-shaped braces for reinforcing said angular portions of the standards, a platform between the standards, pulleys or sheaves upon the upper portions of the-standards or supports, ropes or chains passing over said pulleys having one end secured to said platform, and power means for winding the other end of the ropes or chains to raise and lower the platform.

5. A log-handling machine comprising a platform or floor, a plurality of vertical standards or supports having their lower ends bent to form right angles and extending partly under said platform, triangularshaped reinforcing-plates for said angular portions of the standards, wheels or sheaves on the-upper ends of said standards, ropes or chains passing over said pulleys having one end fastened to said platform, a plurality of drums or pulleys extending from "the edges of the platform having the other ends of the ropes wound thereon, shafts for the drums, a prime mover, and belt means from said prime mover to the said drum-shafts for moving the platform. p

6. A log-handling machine comprising a platform, lattice-braced girders beneath said platform having their ends protruding beyond the sides thereof, channel plates or bars between said girders, a plurality of angleended platform supports or standards slidably mounted in said channel-plates, pulleys on the upper portions of 'said supports, ropes or chains passing over said pulleys, means for raising and lowering said platform by the ropes, means for supporting said platform, pulleys on the lower portions of the supports,

ropes passing around said pulleys having one end secured to said platform, means for lifting said standards when the platform is supported, a plurality ofdrums for winding the free ends of said ropes, shafts for said drums, ratcl1et-andpawl means for holding said shafts when the platform is elevated, and connecting means from said drum-shafts to a source of power.

In testimony whereof I have hereunto affixed my signature in the presence of two wit nesses.
